Abstract
The utility model discloses a safety syringe needle exclusively used for a heparin cap. The safety syringe needle exclusively used for the heparin cap comprises a needle pipe and a needle stand. A sleeve is provided outside the needle pipe, and the axle center of the sleeve and the axle center of the needle pipe are superposed. One end of the sleeve is fixed on the needle stand, and the other end of the sleeve is an open end. The length of the sleeve is greater than the length of the needle pipe. Internal threads are arranged on the open end of the sleeve. Since a needle point is in the sleeve, fingers cannot be accidentally injured by the needle point. In case of need, the syringe needle can be fixed with the heparin cap simply by enabling the sleeve to rotatably connect to the backseat of a conical pipe of the heparin cap. The operation is convenient.
Description
Technical field
This utility model relates to medical appliance field, specifically a kind of syringe needle being used in conjunction with calparine cap.
Background technology
Calparine cap imitates can carry out the effect of good fortune principle to Catheter, to reduce patient's medical expense, improves nurse's work efficiency.Current calparine cap, comprise the conical pipe that is threaded collar, the back seat of conical pipe is inlaid with plug, for entry needle puncture, in the time of dosing or drawing liquid, the entry needle of syringe pierces into plug to tube for transfusion liquid medicine injection or extracting bodily fluid, but, because the target of plug is less, entry needle is not easy aligned position, easily stabs finger.In addition, in infusion process, entry needle and calparine cap need to be fixed, existing mode is with Medical adhesive plaster, entry needle and calparine cap stickup to be fixed, and above-mentioned fixed form is easily loosening, reduces work efficiency, even can cause malpractice.
Summary of the invention
The purpose of this utility model is to provide a kind of safety needle that is exclusively used in calparine cap, in the plug portion piercing process to calparine cap, can effectively avoid stabbing finger, and syringe needle and calparine cap can be fixed fast.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of safety needle that is exclusively used in calparine cap, comprise needle tubing and needle stand, there is sleeve in needle tubing outer setting, the axis coinciding of described sleeve and needle tubing, sleeve one end is fixed on needle stand, the other end of sleeve is opening, and the length of sleeve is greater than the length of needle tubing, and described sleeve openings end is provided with female thread.
The beneficial effects of the utility model are:
This utility model, because needle point is in sleeve, avoids needle point to accidentally injure finger, if syringe needle and calparine cap need to be connected and fixed, as long as the conical pipe back seat of sleeve and calparine cap is spun, easy to operate.
